ATTACHMENT FOR SEED-DRILLS.

Specification of Letters Patent.

Patented Apr. 28, 1914.

Application filed June 21, 1913. Serial No. 775,021.

To all whom it may concern Be it known that I, ARTHUR BOTTOM, a

subject of the King of Great Britain, residing at Throne, in theProvince of Alberta, Dominion of Canada, have invented certain new anduseful Improvements in Attachments for Seed-Drills; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such will enable others skilled in the artto which itappertains to make and use the same.

This invention relates to improvements in seed drills.

The principal object is to provide a simple device for attachment to aseed drill which will hold thefurrow open to permit the seed to settleto the bottom, and then press the seed to a uniform depth.

Other objects and advantages will be apparent from the followingdescription when taken in connection with the accompanying drawings.

In the drawings: Figure 1 is a side elevation of a portion of a graindrill showing my invention applied. Fig. 2 is a rear elevation of thesame. Fig. 3 is a top plan view. Fig. 4 is a vertical section on theline AL- l of Fig. 1. Fig. is a side elevation of a modification. Fig.(5 is a rear elevation of the same.

Referring particularly to the accompanying drawings, 10 represents oneof the seed tubes of the grain drill, while 11 represents the furrowopening disks which are disposed in advance of the said tube 10. Securedto the lower end of the tube 10 on either side thereof and extendingrearwardly from the tube are the vertically disposed plates 12, theseplates converging slightly downwardly toward each other and running inthe furrow. Each of these plates 12 is formed with a slot 13. Secured inany suitable manner to the drill tube 10 and a suitable height above theplates 12 is a rearwardly extending arm 14, the outer end being formedwith an elongated slot 15 to receive therethrough the vertical pin. 16carried by the upper end of a fork 17. Rotatably mounted in the lowerportion of this fork is a double convex wheel 18, this wheel rotatingbetween the plates 12 and running in the furrow. The lower end of eachof the arms of the fork carries a pin 19 which is slidably engaged inone of the slots 18. Carried on the pin 16, and disposed between the arm14- and the upper end of the fork 17 is a coil spring 20, this springnormally holding the wheel 18 in the bottom of the furrow. Connected tothe rear of plates 12 and dragging therefrom are the covering chains 21.

In Figs. 5 and 6, I have shown a slight modification in which I dispensewith the arm 1 1 and the fork 17, this fork being replaced by the fork22 secured directly to the seed tube 10. The furrow is opened by thedisks 11, and the seed is deposited in the furrow from the lower end ofthe tube 10, and between the forward ends of the plates 12, these platesguiding the seed, so that it is deposited in the center of the furrow,and also holding the furrow walls apart and preventing the earth fallingthereinto with the consequent danger of seed being deposited on suchsoil.

In the ordinary drills, some of the seed reaches the bottom of thefurrow, but other seed falls on top of the earth which falls back intothe furrow. In this way the seed is not planted at a uniform depth, sothat some of the seeds get better starts than others. Now by means of myinvention, the walls of the furrow are prevented falling back into thefurrow, so that the seed from the tube 10 is free to fall to the bottomof the furrow, the wheel 18 rolling over the seed and pressing the sameto a uniform depth in the furrow. The chains 21 dragging behind theplates 12 thus causing the loose earth at the sides of the furrow tofall into the furrow and cover the seed.

"What is claimed is:

The combination with the seed tube of a grain drill, of a pair of platessecured to the lower end of the seed tube and extending rearwardlytherefrom, said plates converging downwardly and disposed to move in afurrow, each of said walls being slotted, a spring depressed forkcarried by the tube, means on the fork slidable in the said slots, and aseed pressing wheel mounted in the fork and moving in the furrow betweenthe plates.

In testimony whereof, I affix my signature, in the presence of twowitnesses.
